Definitions

  • the present invention relates to a traction-type clutch bearing device, particularly for a motor vehicle.
  • This type of bearing works by traction and in permanent contact and with the rear face of the diaphragm of the release device by means of an annular piece called an engaging piece. Outside the periods of actuation of the clutch device, the permanent contact is ensured by means of a slight axial prestress.
  • French patent application No. 2,545,172 makes known a clutch bearing device of this type, possessing a retaining ring engaged in a groove made either in the engaging piece or in the rotating inner raceway of the thrust bearing.
  • the thrust bearing is mounted on the release mechanism simply by snapping in the retaining ring. It is removed by exerting a push on the thrust bearing, thus causing the retaining ring to retract after passing over studs integral with the engaging piece.
  • a comparable device is also found in the German Patent Application published under No. 3,113,463.
  • the subject of the present invention is a traction-type clutch bearing device which makes it possible to connect or disconnect the clutch bearing and the engaging piece linked to the diaphragm, simply by actuating the thrust bearing axially by means of its control member, and the fitting and removal operations can be carried out "blind", the thrust bearing remaining enclosed in a housing, all this being achieved without any tool, without the risk of incorrect actions and without the need for prior removal of the diaphragm or of any other element.
  • the traction-type clutch bearing device comprises an engaging piece maintained in permanent contact with the clutch diaphragm by elastic means, a thrust bearing which can slide axially on a guide tube under the action of a control member, and axial connection means interacting with a retaining groove made either in the engaging piece or in a member of the thurst bearing and making it possible to connect the thrust bearing and the engaging piece to one another by means of snapping-in, whilst at the same time allowing removal by moving aside.
  • the connection means comprise a ball cage having a plurality of balls mounted between the engaging piece and the thrust bearing and capable, in the connected position, of interacting with a wedging zone and the said retaining groove, thus ensuring axial and rotary locking.
  • the balls of the ball cage are capable of interacting with a release zone.
  • the wedging and release zones are made either on the abovementioned member of the thrust bearing or on the engaging piece.
  • the ball cage which can advantageously be made of plastic, has a certain elasticity. It is provided with a plurality of receptacles for the balls, each receptacle preferably having axial dimensions greater than the diameter of the balls. In this way, the balls can move axially relative to the ball cage during the fitting and removal operations.
  • Each receptacle of the ball cage has two elastic retaining lugs for the corresponding ball, these tending to position the ball in such a way that the original diameter of the balls as a whole corresponds to the connected position, that is to say to the operating position of the clutch bearing device.
  • Means of blocking the ball cage axially during removal are also provided, the balls then interacting with the abovementioned release zone.
  • the ball cage also preferably has a chamfered peripheral zone making it possible to precentre the ball cage during fitting.
  • Each wedging zone for the balls consists of a first cell preferably obtained by machining without removal of chips and having, on a radial plane, a radius of curvature greater than that of the balls of the ball cage, to ensure the desired wedging and connection.
  • each release zone consists of a second cell again preferably obtained by machining without the removal of chips and opening into the first cell. The second cell has a cavity greater than that of the first cell, thus making it possible to produce the release zone for the balls.
  • Elastic axial-stop means are also provided to limit temporarily the relative axial movement of the thrust bearing and the engaging piece during assembly, producing a hard point to allow the balls of the ball cage to ensure effective connection after snapping-in.
  • the wedging and release zones are made on the inner periphery of part of the inner raceway of the thrust bearing.
  • the retaining groove is made on the outer periphery of the engaging piece.
  • the outer periphery of the engaging piece also has a release groove for moving aside the balls during the removal operation. ation.

  • the ball cage also advantageously has an axial bearing rim interacting with the end of the inner raceway of the thrust bearing.
  • the wedging and release zones are made on the inner periphery of the engaging piece, and in this case the retaining groove is made on the outer periphery of part of the inner raceway of the thrust bearing.
  • the ball cage simply has an axial bearing rim interacting with the end of the engaging piece.
  • this locking piece can occupy two axial positions. In a first position, the ball cage can move up to its connected position. In a second position, the balls of the ball cage can interact with their release zone.
  • the piece for the axial locking of the ball cage is advantageously fastened to the engaging piece by being snapped in elastically and can pass from the first position to the second position as a result of a simple axial push of the thrust bearing.
  • the piece for the axial locking of the ball cage is an integral part of the elastic means of retaining the engaging piece, which comprise a curved washer provided with a plurality of lugs constituting the said axial locking piece.

  • the engaging piece 1 also has an annular sleeve 18 possessing an outer slot 19 which receives snap-in lugs 20 integral with the elastic member or curved washer 14.
  • the engaging piece 1 is therefore fastened by elastic clamping by means of the member 14, the fingers of the diaphragm 13 being gripped between the bearing collar 17 of the engaging piece 1 and the elastic connection member 14.
  • the axis of the engaging piece 1 is precentered relative to the axis of rotation of the diaphragm 13 by means of a mutual fit with a suitable play between, on the one hand, the bore of the fingers of the diaphragm 13 and the diameter of the sleeve 18 of the engaging piece 1 and, on the other hand, the bore of the fingers of the diaphragm 13 and a cylindrical portion 21 of the elastic member or curved washer 14.

  • Each receptacle 22 of the ball cage 3 has two elastic retaining lugs 26 which grip the balls 23 on each side over the entire axial length of the receptacle 22, thus ensuring that the balls 23 are retained by means of wedging. However, the latter can move radially in their receptacle 22 as a result of the elasticity of the retaining lugs 26.

  • the ball cage 41 also has an axial bearing rim 44 capable of interacting with an annular groove 45 made in the bore of the engaging piece 36 at the end of the axial sleeve 39. It will be seen that, in this embodiment, the end face 46, opposite the rim 44, of the ball cage 41 has no locking bead.
  • An axial locking piece 47 which, in FIG. 10, takes the form of a cup provided with a radial edge 48 and an axial edge 49 composed of a plurality of lugs is fastened to the end of the engaging piece 36 by means of pegs 50, each peg 50 extending one of the lugs of the edge 49.

It will also be noted that, during these operations, the ball cage 41 is kept locked axially relative to the engaging piece 36 by means of its bearing edge 44 which is located in the groove 45. The axial locking piece 47 is in its first position, in which the pegs 50 interact with the first groove 51, thus allowing the ball cage 41 freedom of axial movement.

  • the operator first exerts an axial push on the thrust bearing 32 by acting on its control member 11 so as to bring the thrust bearing 32 closer to the diaphragm 13, until the hard point corresponding to contact between the stop piece 53 and the collar 47 appears. The operator continues his action beyond this hard point, thus causing the elastic deformation of the lugs of the edge 49 of the piece 47, the pegs 50 of which escape from the groove 51 to the extent that they snap into the second groove 52.
  • the transfer from the first groove 51 to the second groove 52 is illustrated in FIG. 12a. It will also be seen in this figure that the push on the thrust bearing 32 drives the balls 43 and the ball cage 41 because of the retaining groove 35, the bearing rim 44 progressively penetrating into the groove 45.
  • FIG. 12b The final position in the pushing action is illustrated in FIG. 12b, where it will be seen that the pegs 50 have penetrated into the second groove 52, whilst the rim 44 is inserted completely into the groove 45.
